FLUID-PRESSURE REGULATOR.

SPECIFICATION formingpart of Letters Patent N 0. 571,913, dated November24, 1896.

Application filed September 19, 1895. Serial No. 562,968. (No model.)

T 0 all whom it may concern:

Be it known that I, EDWARD BADER, a citizen of the United States, and aresident of the city of St. Louis, in the State of Missouri, haveinvented a certain new and useful Improvement in Pressure-Regulators, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecification.

My invention relates to that class of regulators or engine-governorsemployed to control the varied pressures in different parts of a steam,compressed-air, or other system of pipes or to control the speed ofengines, the object of my invention being to provide a valve which willoperate with slight power and which is so balanced on both the high andlow pressure sides that it will easily respond to the least variation inpressure at the lowpressure side falling below the normal predeterminedlimit; and my invention consists in features of novelty hereinafterfully described, and pointed out in the claims.

Referring to the drawings, Figure I illustrates a side elevation of myimproved pressure-regulator, a portion of the auxiliary cylinder andpiston being shown in vertical section. Fig. II is a top view of theside of the regulator shown in Fig. I. Fig. III illustrates a verticalsection taken through the regulator. Fig. IV is aview of the valve-seat.Fig. V is a view of the valve. Fig. VI is a crosssection taken on lineVI VI, Fig. V. Fig. VII is an edge view of the valve.

In the drawings, 1 designates the housing,

and 2 the supply or high-pressure side opening, and 3 the delivery orlow-pressure side opening.

4 designates a cap secured to the housing by means of screw-bolts 5, andintegrally formed with said cap is an inwardly-extending sleeve 6, thatis screw-threaded upon its interior and is designed to receive the stem7 of a plate 8, which stem is screw-threaded to engage the sleeve 6. Theouter end of the stem 7 protrudes beyond the outer surface of the cap 4,where it is provided with a nut 9 and a packing-nut 10,the nut 9 bearingagainst an annular flange 4 on the cap 4.

11 designates a valve-seat removably set into the housing 1 in thepassage between the supply and delivery openings 2 and 3. Thisvalve-seat 11 is provided with ports 12.

14 designates a valve located between the valve-seat 11 and the plate 8and provided with recesses 15, that are arranged to be turned intoregistration with the ports 12 to form passage-ways from the supply sideof the regulator to the delivery side. The valve 14 also has recesses 16at the opposite face from that in which the recesses 15 are located, andit is through the medium of these recesses 15 and 16, located at theopposite sides of the valve, that I obtain the result of the quickaction of the valve on the variance of pressure at the low-pressure sideof the regulator. Owing to the fact that the valve being provided withrecesses at each side the steam or other medium at both the high and lowpressure sides is exerted upon each face of the valve, and as aconsequence the valve is absolutely balanced and thereby caused to movereadily on a slight variation from the proper degree of pressure.

The valve 14 is provided with a central square opening 17, that isdesigned to receive the square portion 18 of a stem 19, whose inner endis seated in the cavity 13 of the valveseat 11. The outer end of thestem 19 has attached to it a crank-arm 20, that is connected by a link21 to a pivoted lever 22,'

provided with an adjustable weight 23. Connected to the lever 22 is apiston-rod 24, that carries a piston 25, operating in an auxiliarycylinder 26. The auxiliary cylinder is open at its upper end, and at itslower end is provided with connection to a pipe 27, that leads to anydesired portion of the delivery-pipe at the low-pressure side of theregulator. By the employment of the adjustable plate 8 I am enabled toadjust the fitting of the valve I to a nicety and prevent any leakage atthe valve, and in the event of the valve being reduced by grinding tosmooth its face it is readily adjusted on being replaced.

The'operation of my device is as follows: The weight 23 is arranged uponthe lever 22 at the proper position to gage the desired pressure ofsteam or other medium, and when the medium has been turned into thedelivery-pipe the valve 14 will be entirely opened owing to the factthat the weight 23 is at its ICO lowest position, (owing to there beingno pressure exerted in the cylinder 26 to sustain it,) and the mediumwill pass through the valve to the low-pressure side until sufficientpressure has entered the lowpressure side to raise the weight 23 bypressure upon the under side of the piston 25. The elevation of thepiston'will raise the lever 22 and the link 21, which link in its turnwill operate the crank-arm 20 and the valve-stem l9 and close the valve14, thus wholly'or partially shutting off the passage through theregulator, and as the pressure varies on the lowpressure side the valve14 will be caused to vibrate accordingly.

I claim as my invention- 1. In a pressure-regulator, the combination ofa housing, a valve-seat in said housing, a valve provided with recessesin both of'its side faces, which are arranged out of transverse linewith each other and means for operating said valve, substantially asdescribed.

2. In a pressure-regulator, the combination of a housing, a valve-seatin said housing, a valve provided with recesses in both of its faces,said valve being arranged in contact with said valve-seat, and anadjustable plate arranged in contact with the face of said valve,opposite said valve-seat, substantially as and for the purpose setforth.

3. In a pressure-regulator, the combination of a housing, a valve-seatprovided with ports, a valve provided with recesses in both of itsfaces, and means arranged to operate said valve; said means consistingof a weighted lever, a piston connected to said lever, a cylinder inwhich said piston is arranged to operate, and connection from saidcylinder to the delivery side of the regulator, substantially asdescribed.
